观察细节
Hard to identify most of the tattlers seen without good views, but my guess would be the majority were this species. A single bird seen well is identified as T. incana here based on: 1) calls, a rapid unslurred "dudududoit" (as written in the field) together with a "poo-eet" alarm call. Listening to recordings several weeks later and trying to recall from memory is problematic but reviewing calls after coming out of the field this seemed distinctly different from recordings of T. brevipes. 2) primary projection, with wing tips obviously extending beyond tip of tail. 3) habitat, potentially also a useful bit of contributing evidence, this bird was singleton on a rocky river edge, as opposed to large flocks of T. brevipes seen on sand flats on other parts of the island. Photos of one individual, but a second (not photographed) seen and heard more clearly.
